Manual Addendum
SETUP PROCEDURE FOR "WET-FLOW CALIBRATED" 1010 SYSTEM
Caution: DO NOT use the field manual installation procedure to startup a wet-flow
calibrated system. Doing so could void the calibration by corrupting es-
sential data. This addendum contains the only authorized instructions to
be used when commissioning a wet-flow calibrated 1010 system.
1. INTRODUCTION
When the system 1010 is wet-flow calibrated, the flow computer stores the installation param-
eters in its storage memory. Each flow calibration is assigned a unique site name. Usually, the
site name corresponds to the pipe size. For example, a 3-inch carbon steel, schedule 40 pipe
would be given the name "3CS40."
The flow calibration report issued with each wet-flow calibration, includes a flow calibration
"Diagnostic Data Sheet." This data sheet lists the site name and other necessary information
(such as transducer serial number and spacing information), for setting-up the flowmeter. A
wet-flow calibration applies to a specific flowmeter and set of transducers; identified by serial
numbers on the diagnostic data sheet.
NOTE: In order for the flow calibration to be valid, the flow computer and transducers
being used must have the same serial numbers as those listed for the site on
the Calibration Diagnostic Data Sheet.
2. SETUP PROCEDURE
2.1 Transducer Installation
2.1.1 Refer to the diagnostic data sheet to find the mounting mode (Direct or Reflect) used
during the wet-flow calibration. Review the transducer installation guidelines in your 1010
field manual.
2.1.2 Refer to the diagnostic data sheet for the transducer spacing index utilized during the
flow calibration. Using the mounting configuration employed during the flow calibration,
install the transducers on the pipe at the above noted spacing positions in accordance
with the instructions provided on the transducer installation drawings.
2.1.3 Attach the transducer cables noting that the cable marked "UP" attaches to the trans-
ducer closest to the source of flow.
NOTE: Before proceeding further, ensure that the pipe is full of liquid. It is not impor-
tant at this point that it be flowing.
